Quantifying the Effectiveness of an Interactive Physics Problem Library

题目：量化交互式物理问题库的有效性机构：麻省理工学院i: David E pritchard该项目建立在先前国家科学基金会资助的基于web的交互式问题库的基础上。在过去的几年里，项目库已经发展起来，已经积累了近1000个交互式的、教学上合理的、介绍性的物理问题库。这些问题已经在几个环境中进行了测试，最近Addison-Wesley以“精通物理”的名义授权了整个系统，并将其包含在几个介绍性物理文本中。尽管取得了这些成功，但该库并没有得到更广泛的采用。这个项目向更广泛的受众展示了他们互动辅导理念的有效性。在这个项目中，交互式辅导系统正在全国各地的一些机构进行测试，使用严格的教育研究技术来确定该系统的用户比传统的书面作业或其他作业系统获得的有效学习收益。这些研究的结果正在准备发表在同行评议的期刊上，并为物理教师和物理教育研究界做报告。我们将在项目的第一年发表几篇期刊文章来展示结果。

ABSTRACTProposal #: DUE-0231268Title: Quantifying the Effectiveness of an Interactive Physics Problem LibraryInstitution: Massachusetts Institute of TechnologyPI: David E PritchardThis project builds on previous National Science Foundation funding of a web-based interactive problem library. The project library has been developed over the past several years and has amassed a library of nearly 1000 interactive, pedagogically sound, introductory physics problems. These problems have been tested in several settings, and recently Addison-Wesley licensed the entire system under the name "Mastering Physics" for inclusion with several of its introductory physics texts. Despite these successes, the library has not been more widely adopted. This project demonstrates, to a wider audience, the effectiveness of their interactive tutoring concept. In this project the interactive tutoring system is being tested at a number of institutions around the country using rigorous educational research techniques to determine the effective learning gains enjoyed by users of this system over traditional written homework or other homework systems. The results of these studies are being prepared for publication in peer reviewed journals and presentations for physics instructors as well as the Physics Education Research community. We will publish several journal articles within the first year of the project demonstrating the results.
